T-Mobile has confirmed via twitter what other sources have told us: the Dell Streak 7 Android tablet will launch on Groundhog Day. On Feb. 2 you can get a 7" Android OS 2.2 Froyo tablet with an 800 x 480 pixel Gorilla Glass display and a dual core Tegra processor for only $199 with contract and $450 without contract. Odd that the no-contract price is cheaper than the 5" Dell Streak.

The Streak 7 will run Dell's nifty looking Stage UI and it will be OS upgradable though there's no concrete statement yet about Honeycomb OS 3. It has HSPA+ 4G which gives it some traction against the popular and more expensive Samsung Galaxy Tab. The 1GHz dual Core Tegra 2 is the Streak's other advantage, though it's lower display resolution hurts (the Tab is 1024 x 600).

Other goodies include the usual WiFi 802.11n, Bluetooth and a GPS. No, it doesn't make cellular phone calls.
